Sample size is the only meassurement for greatness!
You cannot be considered GOAT it you had a micro career and moreover a micro prime with a hand full of fights! For example Cains prime consists of maybe 2-3 years where he had like 7-9 fights against 5 guys, so how in hell could anybody value this over someone like Anderson who had over 10 title defenses, not counting his way to the top?
Today we have a lot of fight fans and many of them chose their favorite fighter not on their results but because they feel somehow connected to them, either through nationality, race or culture and they try their best to justify why they think their guys are better than others, which results in them making up intangible criteria for goatness, like “never been cut” for example, which has nothing to with how anyone not having down syndrom should evaluate someonea career.
